Translate Forum?

Hi, I copied my language files from D7.0.9 forum to D7.1b1. Now I see under manage forums "compile language: en", "compile language: de" and "compile language: ru". When I click "compile language: en" it shows a javascript windows reading that language was complied. Clicking on "compile language: de" does nothing at all. Anyone an idea?

if you need a complete german translation for D7.1 osho please have a look here: http://www.boonex.com/m/german-translation-pack

thanks for you advert, I don't need the translation I need to know why it doesn't compile/work

ok, i think you didnt copy the whole forum translations over ...
